Are there horse archers?

I asked this question a while ago. I played like the very first time this game was available, and I got up to my tier 10 horse archers, which took me a long time. Then that beta/alpha (don't know the difference) stopped, and once it came back, all my progress had been taken away, even though they said we'd keep everything. So I played one game and haven't played ever since, especially since there was no horse archers to work for.

So I have read all the emails they've sent since then, and I want to make sure I get the "Closed Beta Immortals Reward, so I'm actually downloading the game to do that.

However, my question is... have horse archers been added to the game? Also, how do you get the reward? Thanks!

Let's hope that they add a Persian faction in the future, probably them we can have parthian style horse archers in the higher tiers. I really want to relive my days in Europa Barbarorum with horse archers and cataphracts.
